1.Stabilized water pump
- High efficiency and more energy saving
The water pump has excellent performance and high efficiency. The efficiency indicator has reached the international advanced level. The energy efficiency index has reached MEI≥0.7, which is much higher than the national energy-saving standard. It has passed the national pump energy-saving certification.
- Beautiful appearance
The shell is made of stainless steel plate, the outer surface is polished, smooth and beautiful, with a modern flavor
- Corrosion resistance and long life
Adopt new industrial and hydraulic design methods and perform finite element strength analysis. Stainless steel castings are precision cast with silicon melt and have high dimensional accuracy. The rusty iron parts are mechanically shaped with molding sand, and the surface is coated with electrophoretic paint to have a smooth appearance and corrosion resistance.
- Clean and environmentally friendly
The parts are made of stainless steel plates, which is green and environmentally friendly, will not cause secondary pollution of water quality, and meets the requirements of health standards.
The third generation KQDP light vertical multi-stage centrifugal pump is designed with energy saving, environmental protection, safety and reliability as its design concepts, adopts new industrial and hydraulic design methods, and is the latest independently developed new generation product. The products are suitable for different temperature, flow and pressure ranges, and can transport various media from tap water to industrial liquids. They are widely used in water supply, industrial pressurization, industrial liquid transportation, HVAC, irrigation and water treatment and other fields. KQDP is suitable for non-corrosive liquids, and the product complies with GB/T5657-2013 《Technical Conditions for Centrifugal Pumps (III)
2.Fire electrical control cabinet
The specific functions of the fire electrical control cabinet supporting the W series fire booster and regulated water supply equipment are as follows:

3.Unit structure
The W series fire booster and stabilized water supply equipment is based on the number of stabilized water pumps in the equipment unit, one for use and one for standby. The unit pipes are welded pipes, and the pipe connection method is flange connection.
The standard type is a stabilized pump unit (excluding import), control cabinet and pressure tank installed separately. The outlet of each stabilized water pump contains a check valve, a butterfly valve for maintenance, a pressure gauge, a manifold, and a pressure detection component. The safety valve on the main manifold of the unit is optional, and one side can be equipped with a reducing pipe and a metal hose to facilitate connection with the outlet pipe of the on-site pressure tank.
The overall skid-mounted type is a pressure-stabilizing pump unit (excluding imports), control cabinet and pressure tank. It adopts an integral skid-mounted base. The outlet of each pressure-stabilizing water pump contains a check valve, a butterfly valve for maintenance, a pressure gauge, a manifold, and pressure detection components. The safety valve on the unit’s main converging pipe is optional, and the diameter of the main pipe is consistent with the diameter of the outlet of the pressure tank.
